China PN16 CL150 Pressure Flange Type Butterfly Valves Manufacturers, Exporters
Product Description
Our valve can be produced by different kinds of materials, it’s produced by international standard and national standard according to your requirement.
The valve body and inner parts are produced by CNC machine to guarantee the precision of the valve production. It’s an epoxy coating body with good looking appearance.
The valve body is made of QT450 or WCB, and its chemical composition and mechanical properties meet the requirements of national standards. Material reports are available.
🛠 Design & Construction Features
There are rubber soft seals and stainless-steel hard seals to choose from. Parts such as valve plates can also be selected according to the working conditions.
The valve seat is welded by stainless steel, which is more wear-resistant and has a longer service life.
The valve shaft is supported by self-lubricating sleeve bearings, which can reduce the friction and torque generated during the transmission process of the valve shaft.
4-level load elastic seal absolutely guarantees zero leakage inside and outside the valve.
⭐ Product Advantages
Butterfly valves are like ball valves but have more advantages. When actuated pneumatically, they open and close very quickly. Discs are lighter than balls, and the valve requires less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which gives them an advantage in industrial applications. They are very reliable and require very little maintenance.
Easy and fast opening/closing with less force. Has less fluid resistance and can be operated frequently.
The structure is simple, the size is small, and the face-to-face size is short, which is suitable for large-diameter valves.
The sealing surface is generally made of rubber or plastic. Therefore, the butterfly valve has good sealing performance under low pressure.
Butterfly valves are like ball valves but have more advantages. They are open and close very quickly when actuated pneumatically. The disc is lighter than a ball, and the valves require less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.
🌍 Application Areas
Flanged rubber lined butterfly valves are widely used in the transportation of liquids and gases (including steam) in various industries.
Pipelines, especially those used for severely corrosive media such as hydrofluoric acid, phosphoric acid, chlorine, strong alkalis, aqua regia and.
This product is used for the water supply and drainage system in tap water, sewage, building, chemical etc. industries, usually used as an open-close equipment.
